“Addressing the core trait of bipolar disorder”: A concept analysis of mood‐stabilizing drugs

Abstract

AbstractObjectiveThe term “mood stabilizer” is controversial in the literature and criticized for being imprecise and overly inclusive, having its retirement suggested to avoid misuse. Nevertheless, it continues to be employed as it may still carry important meaning.MethodsWe employed document analysis for reviewing relevant definitions of mood stabilizer employed in the literature. Then, we clarify the meanings associated with the term by employing evolutionary concept analysis. Based on its results, we present a theoretical model for a mood stabilizer and further match it with evidence gathered from published meta‐analyses and other sources for drugs used in the treatment of bipolar disorder.ResultsConcept analysis unearthed four attributes of a mood stabilizer that were nested into the following ascending hierarchy: “not worsening,” “acute effects,” “prophylactic effects,” and “advanced effects.” “Prophylactic effects” were often considered the core aspect of a legitimate mood stabilizer.ConclusionThe proposed model uses a hierarchy of attributes that take into account the complexity of the term and help to determine whether a drug is a mood stabilizer. Prophylaxis is pivotal to the concept, whose utility lies in implying a drug able to truly treat bipolar disorder, as opposed to merely targeting symptoms. Consistent use of the term could encourage investigation of drugs that modify long‐term outcomes and illness trajectory, instead of simply approaching symptom clusters.
